IMPROVEMENT IN AXLE-LUBRICATORS.

f Specification forming part of Letters Patent No. 93,962, dated August7, 1877; application tiled I v June 23, 1877.

To all whom t may concern:

Beit known that I, LnNsoN JOHNSON, of Vincennes, in the county of Knoxand State of Indiana, have invented certain new and useful Improvementsin Axle Lubrieators and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying' drawings, and to the letters of reference marked thereon,which form part of this specication.

The nature of my invention consists in the construction and arrangementof an axleskein or spindle with oiling device, as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and Operation, referring to the annexed drawings, inwhich-A` Figure l is side elevation, partly in section. Fig. 2 is atransverse section, and Fig. 3 is a detail view ofthe nnt D.

A represents an axleskein or spindle of any ordinary form, provided onthe side or top at the butt-end with an oil-reservoir, B, having a capor cover, C, of sheet or other metal.

From the reservoir B the oil flows the entire length of the skein Athrough a groove, a, made therein, and running quartering or spiral, asshown. The lower side al of this groove extends in a radial direction,while the upper side a2 is beve1ed,so as to facilitate the owing in ofthe oil into the groove as it is carried around the skein by therevolution of the wheel.

D is the nut or tap on the end of the spindle. In this tap is made ahole, b, at such a point that when the tap or nut is reversed or turnedforward said hole may come in line or coincide with the groove a, forthe purpose of inserting a wire or instrument to probe the groove,thereby cleansing the same, and removing any obstructions in the groovewithout removing the wheel. When the nut D, is turned to its properplace the hole b, will be away from the end of the groove a, thuspreventing the oil from running out.

At the butt-end of the skein or spindle, on the under side, is aperforated projecting lug, G, for the purpose of attaching thestaychains. This lug may be either cast on orattached to the skein.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The tap or nut, D, provided with. the hole b, in combination with anaxle-skein or spindle, A, having oil-groove a, substantially my own Iaffix my signature in presence of two witnesses.

LEN SON JOHNSON.
